Lower engine mount questions
 

My lower front torque mounts on my 2001 GSR are completely torn. I am guessing the transmission mount must also be bad. I'm planning on getting new lower mounts next week. I want stiffer torque mounts. I was thinking Megan as they look OEM but use stiffer rubber. I might go with a billet mount with stiff poly bushings. My question is, if I use stiff front torque mounts, do I need to use a stiff rear transmission mount too? Will it cause an OEM rear mount or the upper mounts to fail by shifting the load to the softer bushings?
